US07781936B2 Surface acoustic wave device having gap between surface acoustic wave filters covered by sealer 有权
表面声波装置在由密封器覆盖的表面声波滤波器之间具有间隙

Surface acoustic wave device having gap between surface acoustic wave filters covered by sealer
Abstract:
A surface acoustic wave device includes a base substrate, first and second surface acoustic wave filters mounted on a surface of the base substrate, and a sealer provided on the surface of the base substrate and covering the first and second surface acoustic wave filters. The first and second surface acoustic wave filters include first and second piezoelectric substrates. The second piezoelectric substrate is located away from the first piezoelectric substrate via a gap. This surface acoustic wave device reduces inter-modulation.
Abstract(Chinese):

表面声波装置包括基底基板，安装在基底基板的表面上的第一和第二表面声波滤波器，以及设置在基底基板的表面上并覆盖第一和第二声表面波滤波器的密封器。 第一和第二声表面波滤波器包括第一和第二压电基片。 第二压电基板经由间隙远离第一压电基板。 该声表面波装置减少了互调。
